Merge tag 'vfs-6.19-rc1.autofs' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull autofs update from Christian Brauner:
"Prevent futile mount triggers in private mount namespaces.
Fix a problematic loop in autofs when a mount namespace contains
autofs mounts that are propagation private and there is no
namespace-specific automount daemon to handle possible automounting.
Previously, attempted path resolution would loop until MAXSYMLINKS was
reached before failing, causing significant noise in the log.
The fix adds a check in autofs ->d_automount() so that the VFS can
immediately return EPERM in this case. Since the mount is propagation
private, EPERM is the most appropriate error code"
* tag 'vfs-6.19-rc1.autofs' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs:
autofs: dont trigger mount if it cant succeed
